SHUTTLE TRAP OR GUARD FOR LOOMS.

Application filed September 29, 1922.

To all whom it may concern:

Be it known that I, WILLIAM G. FIsHER, a citizen of the United States,residing at Sunbury, in the county of Northumberland and State ofPennsylvania, have invented certain new and useful Improvements inShuttle Traps or Guards for Looms, of

which the following is a specification.

This invention relates to looms of all types and has for its object theimprovement in shuttle traps or guards for the same, being adapted inthe event of a shuttle flying out of the warp to confine the shuttle inthe trap or guard and deflect it to the shuttle pocket on either side ofthe loom and thus safeguard the operator or bystander. It is animprovement on my patent dated Feb. 14:, 1922, No. 1,406,835.

In the accompanying drawing,

Fig. 1 is a front elevation of the hand rail and lay beam of a loom,with the shuttle guard of my invention attached to the hand rail;

Fig. 2 is an end elevation of the same, looking from right to left inFig. 1,.and showing also the harness, the guard being shown in workingposition in full lines and in open position in dotted lines;

Fig. 3 is a section on the line 3-3 of Fig. 1, parts being shown in oneposition in full lines, and in another position in dotted lines; and,

Fig. 4 is a section on the line H of Fig. 2.

Referring to the drawing, 1 indicates the hand rail, 2 the lay beam, and9 the harness of a loom. Metal hinge-pieces 3 are secured to the top ofthe lay beam, and a shuttle guand, indicated as a whole by the referencecharacter 9, is connected to the hinge-pieces so that it may swing fromthe normal position of the guard, shown in full lines in Fig. 2, tothedotted line position shown in said figure, wherein arms 8 on the ends ofthe guard engage the harness. The guard comprises metal end plates 7, aplurality of curved retaining arms 6, which are spaced apart from oneanother, and a plurality of rods 5 which extend longitudinally of thelay beam and hand rail between the end plates 7 and through suitableopenings in the retaining arms. The end plates and the retaining armsare hinged to the hand rail by a hinge-rod 4, which extends through saidparts and into the hingepiece 3. The retaining arms extend position.

outwardly from the hand rail over the lay beam and thence downwardly topoints adjacent the latter, and the rods which are carried by the armsand end plates are spaced apart in acurved series overlying the laybeam. Plates 7, integral with or secured to the end plates 7, extenddownwardly and outwardly from said plates and form deflectors fordeflecting the shuttle s downwardly, if it flies off of the lay beam inits passage along the latter.

It will be understood that if the shuttle leaves its course, it willstrike the longitudinal rods which will prevent it from flying upwardly,and at the end of the guard it will strike a deflector plate and bedirected into a pocket (no-t shown) at the end of the beam.

When the loom is stopped and it is desired to raise the shuttle guard sothat the operator may have access to the threads, the guard is thrownupwardly, as shown in dotted lines in Fig. 2, and the rods 8 on theguard rest against the harness. If the loom should now be started withthe guard in the position indicated, the movement of the harness willtip the guard and it will drop forward into its full line position shownin Fig. 2. Thus, it is impossible to operate the loom with the guard outof its operative When the guard drops into its operative position, thecatch 10 on the lay beam enters a notch 10 in one of the end plates 7and locks the guard in its lowered position.

What I claim is:

1. In a shuttle guard for looms, end plates having downwardly andoutwardly extending portions, forming deflectors, and a plurality ofbars extending between said end plates and spaced apart in a curvedseries adapted to overly the lay beam of a loom.

2. In a shuttle guard for looms, an openwork frai'ne comprising endplates having downwardly and outwardly extending portions, formingdeflectors, a series of curved retaining members between said endplates, and a series of spaced bars extending between t-he end platesand connected to said bars.

3. The combination with the hand rail and lay beam of a 100111, of ashuttle guard comprising end plates hinged to the hand rail and havingdownwardly and outwardly extending parts, forming deflectors, curvedretaining arms extending from the hand rail over the lay beam and thencedownwardly guard having a part adapted to engage the 10 toward saidbeam, and a plurality of rods harness when the guard is swung upwardlyspaced apart from one another and extendover the hand rail, whereby theoperation ing between the end plates, said rods being of the harnesswill return the guard to nor- 5 connected to said arms. mal position.

4. The combination with the hand rail, In testimony whereof I aflix mysignalay beam and harness of a loom, of a shuttle ture. guard. hinged tothe hand rail and adapted to normally extend over the lay beam, saidWILLIAM G. FISHER.
